- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
- Part 91: General Aviation

NTSB narrative
The private pilot reported that he intended to make two full-stop landings before returning to his home base. The pilot entered the traffic pattern and announced his position as he maneuvered to final approach. The pilot stated that the approach was stable but appeared to be short. He added power and adjusted the pitch for the projected touchdown point beyond the displaced threshold. When the airplane was over the displaced threshold, the stability of the approach was lost. The pilot suspected a swirl of wind or updraft was encountered as the wing raised more than he expected from previous landings at this airport. The pilot tried to regain the runway centerline and level the wings; however, he was unsuccessful. The pilot then made a radio transmission that he was going around. He applied power and raised the flaps (he reported that his intention was to extend the flaps 20o; however, postaccident, the flap position was fully retracted). The airplane rolled to the left and contacted the ground, coming to rest inverted off the side of the runway.
The forward fuselage, left wing and vertical stabilizer were substantially damaged.
The pilot reported that there were no mechanical failures or malfunctions with the airplane or engine that would have precluded normal operation.
Probable cause
The pilot's failure to maintain airplane control during the approach and his delayed decision to go around.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
